--stack_method <str>

Frames combination method (str; default: \'median\'). The full name of this option for the EsoRex configuration file is fors.fors_img_sky_flat.stack_method [default = median].

--minrejection <long>

Number of lowest values to be rejected (long; default: 1). The full name of this option for the EsoRex configuration file is fors.fors_img_sky_flat.minrejection [default = 1].

--maxrejection <long>

Number of highest values to be rejected (long; default: 1). The full name of this option for the EsoRex configuration file is fors.fors_img_sky_flat.maxrejection [default = 1].

--klow <float>

Low threshold in ksigma method (float; default: 3.0). The full name of this option for the EsoRex configuration file is fors.fors_img_sky_flat.klow [default = 3.0].

--khigh <float>

High threshold in ksigma method (float; default: 3.0). The full name of this option for the EsoRex configuration file is fors.fors_img_sky_flat.khigh [default = 3.0].

--kiter <long>

Max number of iterations in ksigma method (long; default: 999). The full name of this option for the EsoRex configuration file is fors.fors_img_sky_flat.kiter [default = 999].

Note that it is possible to create a configuration file containing these options, along with suitable default values. Please refer to the details provided by the 'esorex --help' command.

An overview over the existing ESO pipelines can be found on the web page http://www.eso.org/sci/software/pipelines/.

Basic documentation about the EsoRex program can be found at the esorex (1) man page.

It is possible to call the pipelines from python using the python-cpl package. See http://packages.python.org/python-cpl/index.html for further information.
